The downstream migration of 46–66 cm radio‐tagged adult pikeperch Stizostedion lucioperca , in the River Gudenaa, Denmark, from late September to late December, coincided with a reduction in the frequent occurrence of prey fish in the tagging area, and hence was interpreted as a feeding migration. The upstream migration from March to mid‐April in spring took place prior to spawning which occurred from late April to June.
